Water retention on the surface of apples and sweet cherry leaves and fruits

open access: yesJournal of Plant Protection Research, 2022
Surface water retention of leaves and fruits of apple (Malus domestica Borkh.) and sweet cherry (Prunus avium L.), was evaluated under controlled environmental conditions in order to determine the retention potential at different growth stages. Dipping

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Preparation of all-organic superhydrophobic PTFE/epoxy composite coatings

open access: yesCailiao gongcheng, 2020
Superhydrophobic coatings with micro-nano hierarchical structure constructed by nano particles usually have a poor behavior in water impact situation. This weakness limits superhydrophobic coatings' outdoor potential applications.

Nitride‐Reinforced Metal Matrix Nanocomposite Powders Production by Plasma‐Assisted Thermochemical Treatment of Intermetallic Powders

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...
